Abstract

The effect of coupling of sowing date and planting density on the mortality of overwintering wheat seedlings was studied by using D-status design.The results showed that the mortality of wheat seedling was the least when being sowed on 25th,October with the seedling density of 80000 plants/667m2.Late seeding and low seedling amount could decrease the mortality.Sowing date had more effect on mortality than seedling amount.
